JAMES A. WATSON, OF WINNIPEG, MANITOBA, CANADA, ASSIGNOB T JAMES A. WAT- SON AND GEORGE A. POWELL,

BOTH OF WINNIPEG, CANADA.

LEACHEB.

Application filed April 28, 1925.

.To all whom it may 'cmwem:

Be it known that I, JAMES A. WATSON, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Leachers, of which the following is the specification.

The invention relates to improvements in leachers and an object of the invention is to provide a leacher particularly adapted for percolating tea and coffee.

A further object of the invention is to provide a leacher of simple construction and pleasing design which will fit the average tea or coffee pot and which can be manufactured quickly and at comparatively small cost and which has a capacity sufficient for the average household purposes.

A further object of the invention is to construct the leacher with a well having a restricted outlet opening therein and provided with an elevated seat for supporting filtering and straining elements, and to supply a removable ring'holding the straining and filtering elements in place, the arrangement being such that the strainer and filter can be readily inserted and replaced.

A further object is to construct the bottom of the well so that the restricted opening is protected against sediment.

With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawingrin which:

ig. 1 is a side view of the leacher mounted on a coffee pot.

Fig. 2 is a plan view of the leacher with the cover thereof removed.

Fig. 3 is a vertical cross sectional view centrally through the lower part of the leacher.

Fig. 4 is a. side view of the ring and handle associated therewith.

Fig. 5 is a horizontal sectional view at 55' Figure 3.

In the drawing like characters of reference indicate corresponding parts in the sevoral figures.

The body 1 of the leacher is formed from metal and is preferably compressed into the shape shown by utilizing suitable dies. The main part of the leacher is substantially cylindrical, the upper end receiving a removable cover 2, whilst the lower end thereof Serial No. 26,471.

curves inwardly as indicated at 3 to a contracted neck 4, the neck being located at the upper end of a. well 5. An internal seat 6 is formed at the base of the neck, that is directly at the top end of the well, and the bottom of the well is fitted with a restricted. centrally positioned outlet opening 7, this outlet opening being preferably in an upstruck portion 8 of the well bottom. By having the outlet 7 elevated in this way, I prevent sediment from getting into the opening 7, the sediment collecting in the lower part of the well.

A straining element 9 of suitable mesh is provided, this being adapted to enter the neck and sit on the seat 6. On top of the straining element I lay a filtering element 10 such as guaze or filter paper and this is preferably cut with alarger diameter than the internal diameter of the neck for a purpose later described.

A ring 11 is also provided, this ring-be ing adapted to pass into the neck and jam the edge of the filtering element against the neck, such arrangement holding all parts snugly in position against the seat 6. A handle 12 is attached to the ring and forms a convenient finger grip which one can grasp when the ring is removed to change the filtering element.

The neck of the leacher is of such a. diameter that it will enter the top opening in a coffee or tea pot indicated at 13. As the lower diameter of the well is considerably smaller than the diameter of the body of the. leacher, the device willaccordingly fit a large range of openings as might occur in varying sized pots. It will be observed that the well is below the strainer.

When the device is to be used, the strainer and the filtering element are put in place on the seat and'then the ring is inserted to hold them tightly in place within the neck. One then puts the required amount of tea or coffee as the case may be, into the leacher and pours in boiling water and applies the cover 2. The water percolates through the tea or coffee and passes through the filteringwashed, 'or cleaned as the ring and strainer can be readily removed to permit of the thorough cleaning of such parts and also of the convenient washing of the interior of the leacher. Each time the leacher is used, a new filtering element is placed above the strainer.

What I claim as my. invention is 1. A leacher comprising a liquid receiving receptacle provided with a removable cover and having the bottom thereof contracted to provide an internal seat and a well beneath the seat, the well being provided with a restricted outlet opening, a strainer resting on the seat, a filtering member covering the strainer and a releasable ring frictionally holding the filtering member and strainer in position against the seat.

2. A leacher comprising a liquid receiving receptacle provided with a removable cover and having the bottom thereof contracted to provide an internal seat and a well beneath the seat, the well being provided with a restricted outlet opening, a strainer resting on the seat, a filtering member covering the strainer, and a releasable ring frictionally holding the filtering member and strainer in position against the seat, said ring being provided with a hand grip.

3. A leacher comprislng a receptacle having its bottom wall depressed to form a Well, the central portion of the bottom of the well being elevated above the remaining portion 'of the Well bottom and provided with an aperture forming an outlet from the well and filter means closing the top of said well and forming afalse bottom for the receptacle whereby the contents of the latter is supported above the well.

lindrical portion to the bottom of the well whereby said well may be caused to fit snugly in openings of various sizes formed in receptacles to which the leacher is applied.

5. In a leacher, a liquid receiving receptacle having the upper end thereof open and the lower end thereof contracted to provide a downwardly extending neck and a well beneath the neck, there being an internal seat formed at the juncture of the well and the neck and a portion of the bottom of the well struck upwardly and that portion thereof provided with a restricted outlet opening.

Signed at Winnipeg, this 9th day of February 1925.
